Cell C are *******! DO NOT TAKE A CONTRACT WITH THEM

Disgusting service, I have tried to cancel my contract for 5 months now, however cell c is still not cancelling it and have debited me over R1000, i keep on getting promised a team leader will call me, my complaint will be investigated, they will listen to the calls, and NOTHING every time i call in they have no details on systems regarding my issue and no one has cancelled my policy!
